INNOVATION July-August 2015

Membrane Caustic Modernization Project MG Engineering was engaged to provide detailed

engineering for a new caustic evaporation unit to replace the existing caustic evaporation plant at Canexus North Vancouver. The new caustic unit, supplied by Bertrams Chemical Plants, was designed for a capacity of 800 TPD (100% caustic). The project is expected to reduce steam consumption, and lower operational and maintenance costs. MG’s scope included the design of the caustic unit structure, foundations, MCC Building, pipe bridges and all interconnecting piping between the existing plant and the new process. A 3D model of the caustic unit was created to identify piping/structural interferences. MG was involved in the caustic modernization project from the feasibility and appropriation grade stages through to detailed engineering and construction management. The project has involved 10 APEGBC members as well as technologists and designers. Start-up is expected in the fall of 2015.

Dasque Creek Hydroelectric Project Owned by Veresen, the Dasque Creek Hydroelectric Project is a 12 MW run-of-river project near Terrace that will be undergoing commissioning in 2015. The project is paired with the nearby Middle Creek Hydroelectric Project and will sell its clean power to BC Hydro. The project was developed with great care towards minimizing the impact towards the fish inhabiting Dasque Creek. The project intake features a 180-meter long fish channel to allow Dolly Varden trout to travel freely upstream and downstream of the headpond. The powerhouse houses two horizontal Francis turbines as well as a flow bypass valve that was designed to be capable of passing the full 12 cubic meters flow to prevent excessive fluctuations in the creek level in the event of a sudden shutdown. Companies involved: Veresen, Sigma Engineering, Baumann Engineering, Thurber Engineering, McElhanney, Northwest Hydraulic Consultants, Detmold Consulting, Voith Hydro, Eaton, and BC Hydro.

Transit Oriented Developments The City of Burnaby has adopted a policy of constructing high-quality Complete Streets in its four Town Centres (transit-oriented development) and the first sites have been implemented. Streets have enhanced features such as sawcut concrete sidewalks, pedestrian lighting, cycle tracks for physical separation from traffic, seat- ing, public art, improved bus stops, and landscaped rain gardens for beauty and enhanced water quality. Applying these standards to all streets will encourage the use of active modes and allow trips within the Town Centres to be made entirely on streets of the highest quality. Project owner: City of Burnaby. APEGBC members involved: Stuart Ramsey, P.Eng. and Doug Louie, P.Eng.
